Do I have to wear a swimming cap to go to the hotel swimming pool?

Whether going to the hotel swimming pool or other swimming pools, it is best to wear a swimming cap, which not only protects the water quality but also protects your health. Hair and scalp secrete a lot of oil, sebum and so on. Soluble in water, polluting water quality. Swimming in the water without a swimming cap is not good for yourself and others. If you see some swimming pools that don't require wearing swimming caps, you'd better not go into the water either. Unless it's outdoor tap water.
